METAL CAP FOR B OTTLES OR JARS.

SPECIFICATION formingpart of Letters Patent No. 731,096, dated June 16, 1903.

' Application filed July 11, 1902- a citizen of the United States, and a resident of the borough of Manhattan, in the city and State of New York, have inventeda new and useful Improvement in Metal Caps for Bottles or Jars, of which the followingis a specification.

My invention relates to an improvement in metal caps for bottles or jars, and has more particularly for its object to provide certainnew and useful improvements in the construction and form of metallic caps which are crimped around the necks of the bottles or ars.

A further object is to provide a metal cap of new and improved construction which may be fastened securely to the neck of a bottle or jar in such a way that the cap may be readily removed therefrom when so desired.

In practice it has been found that when the metal capsnow in use have been crimped under an exterior shoulder on the neck of a bottle the space inclosed between the flange of the cap and the bottle-neck below the packing-disk is often sealed sufficiently to retain some of the liquid which is spilled over during the bottling process. This liquid frequently oorrodes the inner surface of the flange and causes a disagreeable deposit on the bottle-surface adjacent to the mouth, presenting an objectionable appearance when the cap is removed.

When the cap above described is used with certain liquids, the effect of the liquid on the metal is even sufficient to entirely eat through the cap-flange.

My invention contemplates a 'metal cap of such construction that a free circulation of air exists above the locking-shoulder, so as to dry up any moisture whichmight be left in the space between the flange and the bottle.

Myinvention further-contemplates the construction of a cap which can be crimped onto the neck of the bottle without materially reducing the diameter of the bottom of the flange, thus facilitating the ready removal of the cap with any ordinary implement and at the same time allowing for a large variation in the size of bottle-necks without impairing the eificiency of the cap.

Serial No. 115,142. (No model) A practical embodiment of my invention is represented in the accompanying drawings,

in which Figure 1 represents a vertical central section through my improved cap, together with the upper portion of the neck of a bottle, the cap being shownin the position which it assumes before its flange is crimped beneath the shoulder on the neck. Fig. 2 is a similar view with the cap crimped in position. Fig. 3 is a view in side elevation of the same. Fig. 4 is a plan view of the blank from which the cap is formed. Fig. 5 is a vertical central section through a modified form of cap in which the bottom of the flange is not provided with the bead or curled portion shown in the previous figures, and Fig. 6 is a side view of the same.

The neck of the bottle is denoted by 1, and it is provided with an annular exterior shoulder 2 adjacent to its mouth.

The cap comprises a top 3 and a depending flange 4, the bottom of said flange being preferably beaded or curled, as shown at 5, for adding strength to the same. The flange 4 of the cap is fitted to be crimped beneath the shoulder 2 of the bottle-neck for locking the cap to the bottle. A packing-disk 6 is inserted within the cap against the top 3 thereof, which packing-disk serves to seal the mouth of the bottle-neck when the cap is crimped in position thereon. As the flange t is crimped beneath the shoulder 2 the bottom of the flange will retain its original'diameter, thus leaving an ample space 7 between the flange and the neck of the bottle for the insertion of any suitable implement when it is desired to remove the cap. A series of perforations 8 are formed in the flange 4 of the cap, which perforations extend from the packing-disk 6 near the top of the flange to a point near the bottom of the same for permitting a free circulation'of air in the space formed between the flange and the mouth of the bottle-neck above the shoulder. This will permit the evaporation of any moisture which might be left during the bottling operation in the said space.

When certain metals are used, it may not be necessary to use a stiffening bead or curl along the bottom of the flange, the caps in this instance being'made similar to the form shown in Figs. 4 and 5.

The cap may be formed by providing a circular blank 9, of sheet metal of the required character, through which blank the perforations 8 are formed. The blank may then be drawn down into the shape of the cap and the curl or head 5 may or may not be formed, as desired.

It is evident that changes might be resorted to in the form, construction, and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but

What I claim is- 1. A metal cap for bottles or jars having a depending flange fitted to engage a shoulder on the neck of the bottle or jar and a series of perforations in the flange extending from near the bottom to near the top thereof, as and for the purpose set forth.

2. A metal cap for bottles or jars having a depending flange fitted to engage a shoulder on the neck of the bottle or jar, a packingdisk within the cap fitted to close the mouth of the bottle-neck and a series of perforations in the flange extending from the packing-disk to a point near the bottom of the flange,as and for the purpose set forth.

3. A metal cap for bottles or jars having a depending flange fitted to be crimped beneath a shoulder on the neck of the bottle or jar, the bottom of the said flange being beaded or curled and a series of perforations in the flange extending from near the top to near the bottom thereof, as and for the purpose set forth.

4. A metal cap for bottles or jars having a depending flange fitted to be crimped beneath a shoulder on the neck of the bottle or jar and a series of perforations in the flange intermediate the shoulder and the mouth of the neck of the bottle or jar.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 10th day of July, 1902.
